On the afternoon of April 13, 2018, a large wave of water surged across Lake Michigan and flooded the shores of the picturesque beach town of Ludington, Michigan, damaging homes and boat docks, and flooding intake pipes. Thanks to a local citizen’s photos and other data, NOAA scientists reconstructed the event in models and determined this was the first ever documented meteotsunami in the Great Lakes caused by an atmospheric inertia-gravity wave.
Climate change is causing significant impacts on the Great Lakes and the surrounding region. As the largest surface freshwater system in the world, the Great Lakes have an enormous impact, seen and unseen, on the more than 34 million people who live within their collective basin. Because of their unique response to environmental conditions, Earth’s large lakes are considered by scientists as key sentinels of climate change. A long-term study published in Nature Communications today from NOAA reveals a warming trend in deepwater temperatures that foreshadows profound ecological change on the horizon. While less visible than the loss in ice cover and increasing lake surface temperatures, this latest index of climate change adds to the growing evidence of climate change impacts in the region.
New research by NOAA and partners finds that two species of invasive Asian carp -- the bighead carp and silver carp, collectively known as bigheaded carps -- could be capable of establishing populations in Saginaw Bay, Lake Huron and affecting the health of ecologically and economically important fish species such as yellow perch.
NOAA plans to expand its research in the Great Lakes region as the agency teams up with the travel company Viking to carry scientists aboard new expedition voyages planned to begin in 2022.
Two underwater robots will be gliding throughout the western Lake Erie basin this week, as NOAA and its partners at the Monterey Bay Aquarium Research Institute (MBARI) test technology to autonomously monitor and measure the toxicity of harmful algal blooms in the Great Lakes.
In the Great Lakes, summer means the arrival of sun, warmth and time spent enjoying the outdoors. Unfortunately, it also often means the arrival of harmful algal blooms.
Several Great Lakes are expected to reach record high water levels in the next six months, thanks to above average precipitation in the watershed and large amounts of runoff this year.
For scientists at NOAA, Earth Day — and every other day of the year — is about getting to the bottom of some of the most pressing questions about the planet we call home: how it works, how it’s changing, and how humans are affecting it.
